VILLIAM VALENTINE, OF BEDDING, CALIFORNIA.

' TlRE-UPSETTER.

SPECIFICATION formingpart of Letters Patent No. 278,836, dated June 5,1883.

/ Application filed September 1582. (No model.)

To all whom, it may concern:

Be it known that I, XVILLLTM VALENTINE, of Bedding, county of Shasta,State of California, have invented an Improved Tire-Upsetter, and Ihereby declare the following to be 7 a full, clear, and exactdescription thereof.

Hy invent-ion relates to a new and useful tire-upsetter; and it consistsin a stationary block having afixed and a movable jaw, and a slidingblock having similar jaws,though oppositely placed, and an interveninglever so connected with the movable jaws that by its movement in onedirection it separates the sliding from the stationary block afterswinging open the movable jaws, and by its movement in the reversedirection it draws the sliding block with its j aws to the stationaryblock, having previously closed the movable jaws, as will hereinafterfully appear.

The object of my invention is, broadly, to shrink, or, as it is commonlycalled, up set tires. This is a well-known operation, consisting ingripping the tire in two places and forcing the gripping devicestogether, whereby the tire is thickened, and consequently shortened torender it smaller in diameter.

The particular object of my invention is to provide a convenient andeffective device for this purpose, one in which the entire operation ofgripping the tire and shrinking it is per formed by the movement of asingle lever. Referring to the accompanying drawings, Figure 1 is aperspective view of my invention, showing jaws slightly open and blocksseparated. Fig. 2 is a plan of same. Fig. is a longitudinal verticalsection.-

Let A represent a suitable bed-plate, havin at one end beveled sideguides, a.

B is the sliding block. means of beveled base-flanges into the guides a,and is thus adapted to be moved upon the bedplate The block B is spacedor hollowed out, and has within it the plate 0, from the edge of which ajaw, C, with a corrugated face, extends up by the edge oi the block in agroove or notch made therein. The plate 0 is pivoted in the block by ascrew or pin, on, and has upon its sides, extending backwardly by theend wall of the block B, a tongue, 6.

Secured to the edge of the sliding block B, opposite to the jaw O, is afixed jaw, D, having also a corrugated face. Upon the other I move thelever E.

This is fitted by A fixed jaw, D, is secured to the bed-plate and to theside of the block B, as shown.

E is the operating-lever. It is pivoted to the bed-plate about itscenter .and between the two blocksB and B and said plate. lts pivotpinpasses through an elongated slot, 0, in the bed-plate. V W

A link or rod, h, connects the lever upon one side of the fulcrun orpivot wit-h the outer end of plate 0, and another link or rod, 72,connects it on the other side of the pivot with the end of plate 0.

A guide or way, d, is secured to the side of the bed-plate, as shown,for the lever E to rest upon to lend it support.

The blocks B B may be halved into each other to still cover the lever Ewhen the sliding block is moved away from the fixed one.

The operation of my device is as follows: The blocks being together andthe jaws closed, The points of connection of the links h h with thelever being out of line with and closer in than their points ofconnection with the plates 0 c, the first action is to swing said platesoutwardly, thus opening the jaws C G away from the sides of theirblocks. W hen the limit of this movement is reached, which is when therear ends or tongues e c of the plates 0 a come in contact with the endwall of the blocks, the force of the lever closes in the jaws C 0, one011 each side of the tire, and grips it between said jaws and the fixedjaws D D. As soon as the jaws C C are Tak- IOO

stopped the lever forces the sliding block, with its jaws 1), toward thefixed block and jaws (3 D, thus upsetting the tire. The greater theforce put upon the lever the stronger the jaws C C grip the tire, sothat if force enough be brought to bear to move the sliding block thejaws eannot slip on the tire, as they must first bind before the blockmoves. Consequently the greater the resistanee which the sliding blockpresents to the lever the tighter the jaws grip. Therefore I do noteontine myself to the guides 11, but may employ any means by which I mayregulate the friction of-the sliding block upon the bed-plate. To limitthe swinging movement of the jaws ("or to tix them, I have set-screws a,passing through the tongues e 0 of the plates 0 e and impinging againstthe end walls of the blocks B I3.

Having thus deseribed my invention, what I elaim as new, and desiretoseeure by Letters Patent, is-

1. In a tire-upsetter, a stationary block having a fixed jaw, l), and amovable or swing ing jaw, in combination with a sliding block having atiXedjaw, l), and a movableor swinging jaw, as shown, between whieh thetire is gripped, and a means for swinging the movable jaws to grip thetire, and by the same movement to force the sliding blook, with itsjaws, toward the stationary block, consisting of the pivoted lever E andlinks h h for con 2. In a tire-upsetter, a plate, B, having upon it afixed jaw, D, and an oppositelyplaeed movablejaw, (7, pivoted to saidplate '13, in eombination with a. fixed jaw, D, and

movable jaw both upon a sliding frame, and the means for moving thesliding frame, and by the same movement first swinging thejaws C C togrip the tire, consisting of the lGVGl'E, pivoted through a slot, 0, inthe bed-plate, and the pivoted connecting rods or links 71 h, eonneetingsaid lever on each side of its fuleruni with the movable jaws C G, allarranged and operating together substantially as herein described.

3. In a tire-upsetter, the bed-plate A, having at one end guides (I, andthe stationary bloek B, having a. fixed jaw, D, a pivoted plate, 0, andajaw, attached to said plate, in eombination with the. sliding block B,fitted in guides a and having a jaw, 1), secured firmly thereto, apivoted plate, 0, and a jaw, (Y, attaehed to said plate, and the lever Eupon the bed plate A and having a traveling pivotpoint, and the pivotedlinks or rods 71 ll, eon neeting the lever on each side of its fulcrumwith the swinging plates (1 c, all arranged and operating togethersubstantially as herein deseribed.

In witness whereof 1 hereunto set my hand.

\YTLLIAM VALENTINE.
